Discrimination is a harsh word, and I don’t think that’s the message we FFBs mean to project. I have several BT friends (and one Ger)and the thing that strikes me most is the edginess they always seem to be on. Its almost as though they fear a sudden relaps if they loosen up a bit. I fear heaven too, but I don’t quake in my boots every day like its neelah by yom kippur (maybe I should, but that’s another story).
Point is, relax. No one expects the BT to be in better behavoir than the older members. Trying to “out-frum” your teammates gives off nervous vibes, and our reaction to that may be what you’re sensing.
At any rate, rest assured. Us FFBs are also “baale teshuva” on an ongoing basis, so we’re all in the same boat
